Get all the hot (red) molecules to the left chamber, and all the cold (blue)molecules to the right chamber.

Use the up and down arrows to control the thermobaric isomanipulating flux rod (paddle). Press space when the molecules are in the proper chambers to measure the entropy and see if you successfully completed the level!

Be careful! You can only check the entropy a few times. If you check too often, there will be an entropy overload!
